5. Network Transport

   This document provides for the transmission of BLOAT datagrams over
   two common families of physical layer transport.  Future RFCs will
   address additional transports as routing vendors catch up to the
   specification, and we begin to see BLOAT routed across the Internet
   backbone.

5.1. Ethernet

   BLOAT is encapsulated in Ethernet datagrams as in [RFC894] with the
   exception that the type field of the Ethernet frame MUST contain the
   value 0xBEEF.  The first 5 octets of the Ethernet frame payload will
   be 0x3c 3f 78 6d 6c ("<?xml".)

5.2. IEEE 802

   BLOAT is encapsulated in IEEE 802 Networks as in [RFC1042] except
   that the protocol type code for IPoXML is 0xBEEF.
